The clean shirt Nanny puts on Doyle reads "Women belong in the House... and the Senate."
Parts of the interior of the Huntzberger mansion were filmed at Doheny Mansion in Los Angeles, California. The same location can be seen in The Princess Diaries (2001). The Pompeian Room has an iridescent Tiffany glass dome as its core centerpiece which Rory talks about and marble pillars can be seen at the ball that Mia is introduced.
The dinner scene where Logan's grandfather and mother speak rudely to Rory is a bit of a call back to season 2. In the first episode of season 2, Richard treats Dean badly and is upset that Rory has brought him to dinner. In both situations, the guest at the family dinner is deemed to not be worthy.
Sean Gunn (Kirk Gleason) and Gregg Henry (Mitchum Huntzberger) have both appeared in the movie 'Guardians of the Galaxy''. They played Kraglin/On Set Rocket and Grandpa respectively.
Neither Richard nor Emily appear in this episode.
